FAQs About Verification Phone Number Is Not Working

Why can Microsoft reject a phone number, email, PIN, or passkey?

The method may belong to another account, use an unsupported region or number type, be blocked by policy, be out of date, or fail device verification. Record the exact message before replacing it.

Where can account security methods be reviewed?
